The purpose of the meta-analysis was to address the varied and somewhat stratified study results within the area of singing ability and instruction by statistically summarizing the data of related studies. An analysis yielded a small overall mean effect size for instruction across 34 studies, 433 unique effects, and 5,497 participants ranging in age from 5- to 11-years old (g = 0.43). The largest overall study effect size across categorical variables included the effects of same and different discrimination techniques on mean score gains. The largest overall effect size across categorical moderator variables included research design: Pretest-posttest 1 group design. Overall mean effects by primary moderator variable ranged from trivial to moderate. Feedback yielded the largest effect regarding teaching condition, 8-year-old children yielded the largest effect regarding age, girls yielded the largest effect regarding gender, the Boardman assessment measure yielded the largest effect regarding measurement instrument, and song accuracy yielded the largest effect regarding measured task. Conclusions address implications for teaching, research pedagogy, and research practice within the field of music education.

The purpose of this study was to explore adolescent self-views of singing ability through both implicit theories and self-concept meaning systems. A secondary purpose of this study was to examine these self-views specifically in the context of a choral hierarchy. Using a researcher-designed survey instrument, I gathered data from middle- and high-school students currently enrolled in a choir program organized in a hierarchical structure. I analyzed descriptive statistics of survey responses to items designed to measure implicit theories of singing ability, singing self-concept, and goal orientation. I also examined differences among participants by ensemble placement in implicit theory and self-concept scores, correlation between implicit theory and self-concept, and whether implicit theory, self-concept, goal orientation, or current enrollment could predict future enrollment decisions. In addition to these quantitative measures, I coded open-ended responses to two failure scenarios and examined participant responses by ensemble and gender. Both implicit theory and self-concept scores were higher for participants at the top of the choral hierarchy than at the bottom. Open-ended responses, however, did not align with the implicit theory scale and a number of students presented a false growth mindset. Open-ended responses also indicated that failure scenarios were likely to result in an altered view of the self and shame in placement in an ensemble at the bottom of the choral hierarchy. The means scores for participants in the middle- and high-school ensembles in both implicit theory and self-concept were significantly different, with participants in the high-school ensembles having higher scores in both constructs. Implicit theory and self-concept were significantly related, and self-concept, goal orientation, and current enrollment significantly predicted future enrollment decisions.
